    Particle Track
AI Thread Summary
The discussion focuses on two questions regarding particle tracks in a room divided into four quadrants: Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR). For the first question, the correct answer indicating opposite B field directions in TL and TR is identified as B, while for the second question, the correct answer indicating the same B field direction in TL and BL is A. The initial answers provided by the poster were incorrect, leading to the request for clarification. The importance of focusing on the relevant trajectories for each question is emphasized. Clear understanding of quadrant relationships is crucial for solving these particle track questions.

Homework Statement


So there are 2 questions i need help with.
1. Divide the room (for the rest of this valdation) into four (4) quadrants labeled Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR). Which of the four particle tracks indicates that the B field in the TL and TR quadrants are in the opposite direction?
2. Which of the four particle tracks indicates that the B field in the TL and BL quadrants are in the same direction?

The Attempt at a Solution


for number 1, i thought the answer would be C, and two i thought the answer would be D. But i got both answers wrong. I was wondering if someone could help me on these 2 questions.
Thanks.

Problem 1 asks about "top left" and "top right" so only a trajectory that stays in the top half is relevant. Problem 2 talks about the "top left" and "lower left" so only a trajectory that stays in the left half is relevant.
 
SO could you say that for problem one would have to be B, and for problem 2 the answer would have to be A?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
